Microsoft says it resolved a known issue causing erroneous 0x80070643 installation failure errors when deploying the April 2025 Windows Recovery Environment (WinRE) updates. "After installing the April 2025 Windows Recovery Environment update [KB5057588], you might see the following error message in the Windows Update settings page: 0x80070643 – ERROR_INSTALL_FAILURE. In August last year, Microsoft also retired January 2024 Windows security updates that triggered 0x80070643 errors when installing Windows Recovery Environment (WinRE) updates on Windows 10, Windows 11, and Windows Server devices. In an update to the Windows release health dashboard earlier this week, the company said the bug has since been addressed, and the incorrect message will no longer show up after installing the buggy updates. However, before the updates were retired, fraudulent IT support websites were observed pushing malicious PowerShell "fixes" for 0x80070643 errors to infect Windows users with information-stealing malware. The known issue impacts the KB5057588 WinRE update on Windows Server 2022 and KB5057589 on Windows 10, versions 22H2 and 21H2. When it acknowledged the bug two weeks ago, Redmond told those affected that these errors can be ignored since they're inaccurate and don't impact their Windows device's functionality. This error message is not accurate and does not impact the update or device functionality," Microsoft said at the time.
